Parameters that affect performance
Amount of data to build up in memory (backed by an unsorted log
on disk) before converting to a sorted on-disk file.
Larger values increase performance, especially during bulk loads.
Up to two write buffers may be held in memory at the same time,
so you may wish to adjust this parameter to control memory usage.
Also, a larger write buffer will result in a longer recovery time
the next time the database is opened.
